The Senate Judiciary Committee has approved a bill that would force suspects arrested or detained by federal authorities to provide samples of their DNA that would be recorded in a central database. This is a step to expand government collection of personal data, and maybe another step in expanding government intrusion. Currently, only people convicted of crimes must provide a DNA sample. Privacy advocates, including Jim Harper, director of Information Policy Studies at the Cato Institute, oppose the expansion of the FBI-run national DNA registry. Harper is a keynote speaker at the IAPP Privacy Academy 2005 Oct. 26-28 in Las Vegas.
